g++

[Wu zhen hai]

I want to compile gcc source code on windows.

help!

Sorry? GCC does not support Windows. You need to use MinGW or MinGW-64.

But why would you want to recompile it on Windows?

See 'Creating a native Win64 compiler' https://sourceforge.net/p/mingw-w64/wiki2/Native%20Win64%20compiler/

Instructions for building g++ are under the subsection 'Building gcc'
